We installed a CCM on a customer site with a MCS-7835-1000, now we need to change it with a MCS-7835-1266, so we thought to put them in cluster, but the new one (that is going to stay operational) will be the subscriber (read-only mode).
The other way is to reinstall everything from scratch (we hope not to do that).
We already tried to swap the HD from one chassis to the other but it is not working (different hardware... blue screen)
The best way to do that is to put the same version on CM on the 1266 and configure it as a publisher (using the exact same machine name and IP address as the current publisher). You will have to do this on an isolated network as to avoid an IP address conflict.
Then take the latest tape backup of the existing Pub and do a restore on the new Pub. Verify all the data is on the new pub (users, phones, gateways, etc). You can even have a phone register to the new pub (hard code the info on the phone because DHCP won't be running on your isolated network).
Next, power off the existing Pub and put the new Pub into production! Be aware, you may have to re-create the subscription with your existing subscriber (thats why it is very important you use the EXACT same hostname and IP address).
You can swap the drive and recover from the blue screen. Boot off Win2K install. Get the RAID drivers loaded, then run the second(very important) repair option. F8 boot after the install and configure you nic. Reboot. Login. Then Service Pack it and run the CCO updates. and Voila! Restored
Are you getting this error “Installer User Interface Mode Not Supported. The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The value UI mode identifiers...
The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
